.To all whom it may concern:

Be it known that I, VERNON RoYLE, of Paterson, in the county of Passaic and State of New Jersey, have invented .a new and useful Improvement in Edging-Machines, of which the following is a specification. v

My invention relates to an improvement in edgingmachines, with the object in view of placing within the control of the operator such plate clamping and adjusting devices as shall render it feasible to adjust plates of varying size and thickness in the proper relations to the cutter in an expeditious and efficient manner. Y A

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a top plan view of the machine,

showing the several parts in the positions which they may assume in relation to a plate to be operated upon. Fig. 2 is aview indetail, showing in vertical section Aalongthe line 2 2 of Fig. 1 the holder movable later.

Fig. 4 is a View in detail of an auxiliary holder that works in conjunction with the holder represented in Fig. 2, the view being taken in vertical section through the line-4 4 of Fig. 1. Fig. 5 is a view in detail of the rear clamp, showing the same in elevationwith the clamp released. Fig. 6 is a similar View showing the clamp in its closed posit-ion. Fig. 7 is a top plan view of the same. Fig'. 8 is a transverse section through the same.l Fig. 9 is a view in detail, showing the front clamp in side elevation and released from the plate. Fig. 10 is a vertical section through the clamp, showing the same in its clamping position. Fig. 11 is a top plan View of the same. Fig. 12 is a view in detail in side elevation of the gage for indicating the line of cut. Fig. 13 represents the same in end elevation looking from the front of the machine. Fig. 14 represents in detail in side elevation, partly in section, a gage adapted to be swung into and out of position over the table for determining the position of the plateto be operated upon. Fig. 15 is a top plan view of the same when swung into position for use. Figs. 16 and 17 represent views in detail of the cutter-head and cutters, showing the same, respectively, in top plan and in side elevation; and Fig. 18 is a view in detail of the block for holding the cutter in the cutter-head.

In the top plan View represented in Fig. l the different parts of the machine to which my present invention is directed are represented in assembled adjustment, the front of the machine being toward the reader as the drawing is held for reading.

I have not shown the machine-as a whole in elevation, as the parts below the table or below the frame on which the table is mounted form no part of my present invention and may consist of any suitable legs or pedestals of well-known or approved form.

The bed-frame of the machine is represented by A, and on the bed-frame are located ways a a', on which the work-carrying table B is adapted to slide backward and forward to bring the work into engagement with :the cutters c, mounted in the cutter-head C andv rotated by power transmitted from a suitable source (not shown) to a band-pulley to on the spindle c2, which carries the cutterhead O.

For holding the plate D to be operated upon both at its front and its rear ends while being presented to the cutters I provide a front and rear clamp, both of which are adjustable vertically to suit plates of different thicknesses and one of which-in the present instance the rear clamp-is adjustable toward and away from the front clamp to bring its holding-face into position to clamp the edges of plates of Varying sizes.

The front clamp is denoted as a whole by E. It is provided with oppositely-extending arms or jaws, denoted, respectively, by e e', the clamping-faces of which, faced with suitable material-such, for example, as leatherare located at different heights, the face of the jaw e being located at such a height as to adapt the clamp to hold a plate D, with a thick backing D', in position to be operated upon, while the face of the jaw e is suticiently low to adapt the clamp to hold a thin metallic plate three-sixteenths of an inch or less in thickness. The clamp E is mounted in rotary adjustment on a vertically-sliding bar or rod e2, the clamp being held in position IOO on the rod, with its face c or its face e in clamping position over the table, by means of a nut e3 having a screw-threaded engagement with the upper end of the baror rod e2.

To the front of the table B there is fixed a handle B' for the purpose of moving the table forward and backward along the bed-frame A, and beneath the handle B' there is mounted a rocking handle B2, fixed to a rock-shaft e4, mounted in suitable bearings at the front of the table B. There is also fixed to rock with the shaft e4 a short arm e5, the free end of which engages a socket e6 in the rod or bar.

e2, so that as the shaft e4 is rocked it will raise and lower the rod c2 and with it the clamp E. The adjustment is so made that when the rocking handle B2 is drawn toward the handle B' into the position shown in dotted lines in Fig. fl it will cause the clamp E to be thrown into engagement with the plate, and while the hand of the operator grasps the two handles B B2, holding the front edge of the plate firmly in position on the table, the table as a whole, with the plate thereon, may be moved backward and forward without releasing the grasp until the cut has been made. After the cut has been made the release of the operators hand from the handle B2 will permit it to fall, and this movement will release the front clamp from the plate.

The rear clamp is capable of being slid bodily toward and away from the rear edge of the plate along a groove b in the top of the table and comprises a base-piece F, provided at or near its rear end with a pair of upwardly-extending lugs ff', between which there is pivoted the lower end of a link f2. In the upper end of the linkf2 there is journaled, by means of an eccentric f3, a shaft f4, on which are mounted branches g and g of the bifurcated rear end of a lever G, carrying at its front end a clamp g2, provided with a stein g3, having a plurality of perforations g4 located at different heights along the stem for the purpose of attaching the clamp g2 to the forward end of the lever G at different heights to accommodate the clamp to plates of varying thicknesses, as hereinabove described in referring to the front clamp. The clamp g2 may be secured to the lever G byinserting a pin g5 through the end of the lever G and through one or the other of the perforations gl in the stein of the clamp g2. The lever G is fulerumed on a cylindrical pivot g, which extends through the two sides of the lever G and across the spaeeintermediate of the sides, and through this pivot g there extends a vertical bolt g7, having its head qs located beneath the base F in the dovetail groove I) in the top of the table B, and carrying on its upper or threaded end a bearing-washer y and a nut gw, by means of which the fulcrnm of the lever G is varied up and down to give the lever a greater or lesser clamping effect, as may be desired. A spring yu, resting its lower end upon a boss f5, uprising from the base F, and at its upper end against the under side of the pivot 96, serves to hold the lever G at all times in a raised position against the bearing-washer gf.

The rear end of the lever G is raised and lowered to throw the clamp g2 into and out of clamping adjustment by means of a handle H, fixed to rock the shaft f4 in its bearing in the end of the link f2, and the throw of the handle H is limited by means of a stop 7L on the face of the lever G, ywhich stop engages abutments 7L and h2 on the handle, as the latter reaches the limit of its forward and backward throw.

A gage for determining the line of cut or the position which the edge of the plate to be operated upon is to occupy with relation to the path of the cutters is denoted by I. It consists of a fiat strip of suitable material provided with a serrated edge at the front, and is secured to a swinging yoke-piece I by several set-screws t'. An adj listing-screw z" extends through an arm or lug on the yoke-piece If and presses against the back edge of the gage I for the purpose of truing it with respect to the path of the table to great exactness. The yoke-piece I' is mounted in swinging adjustment on eccentric bearings 712 at or near the opposite ends of a rock-shaft i3, which is mounted in the branches t4 of the T supporting-frame i5, the stern i of which is adapted to be locked in the desired vertical adjustment to suit different thicknesses of plates by means of a split socket i7, in which the stem 'i6 slides vertically. The socket i7 is closed and opened by means of a screw 8, as is common, and the T supporting-frame i5 is prevented from displacement in a rotary direction by means of a guide-pin t, which extends from its under side into a socket lo on the frame A. The shaft i3 is rocked by means of an operating-wheel t intermediate ot' its bearings and is held in its rocked adjustment to throw the edge of the gage I more or less toward or over the edge ofthe table B by means of a set-screw i, arranged to close and open one of the bearings 4 in the T-support.

The cutters are commonly set as close as may be to the edge of the table, and the gage I may be made to determine the path of the cutter by setting it in the same relation to the edge of the table which the cutters occupy, or a trial-plate may be run into engagement with the cutters, and then while still clamped the gage may be set up to the path which the cutters traveled along said plate, and thereafter during the operation on a succeeding number of plates the gage I will in each instance locate the path which the cutter is to travel along the plate.

The serrated advanced edge of the gage I when the gage is made of opaque material admits of locating the advance edges of the teeth Very accurately upon a controllingline of the plate, because the operator is able to observe the plate through the spaces between IOO IIO

the teeth for a short distance on the side of the controlling-line toward the gage, as well as upon the opposite side, and thereby is enabled to move the plate a hairs breadth in or out inl order to get the advanced edge of the clamp exactly up to one edge of said line, as the shadow commonly cast by a continuous edge is thereby avoided and the operator is able to see whether the line is or is not partially hidden under the edge.

An adjustableholder for engaging the edges of plates of varying widths opposite the cutter and holding the work up positively against the action ot` the cutter is made to slide toward and away from the cutter along the table B. The body of this holder is denoted by K and is provided with a downwardly-projecting rib la, adapted to slide along a groove b in the table B. The holder K is provided on its end toward the cutters with a swinging auxiliary holding-plate K', which may be thrown down into the position shown in Fig. 2 or turned back onto the body of the holder K to bring the front edge lo of the body of the holder into engagement with the plate, as may be desired. For the purpose of introducing an auxiliary lling-piece K2 (see Fig. l) where it is necessary to push the holding-plate into proximity to the cutters for holding a very narrow plate, I provide the face ot' the auxiliary holder K with dovetailed slots 7a2 for receiving corresponding dovetailed studs on the back edge of the filling-piece K2, so that the latter may be adjusted to the face of the plate K and then turned down into the position shown in Fig. l, with its edge against the plate, leaving at the same time ample room between it and the back gage for manipulating the handle H of the latter and moving it forward and backward, as may be desired.

A swinging dog or stop L (see Figs. l and 4) is mounted on a slide Z, arranged to be slid along the front edge of the table B to adjust it to the position of unusually long and narrow pieces of work and is intended for use iu place of the holder K for holding the work endwise toward the cutter. When not in use, the dog L may be thrown over toward the front, out of the way. The slide Z, which carries the dog, may be locked in its desired adjustment along the front of the table by means of a tail-nut Z' on a bolt Z2, the head of which slides in a groove in the table and the stem of which extends upwardly through the slide Z.

The sliding holder K may be locked to the table B in the desired adjustment toward and away from the cutter by means Lof a hand'- wheel 7c3, having a screw-threaded engagement with a bolt 7a4, the head of which is received in a dovetailed groove b2 in the table B. I have also arranged to coact with the holder K, for the purpose of extending it to adapt itselt to ,plates of varying widths and lengths without unduly extending the holder itself, a sliding plate M, seated in a recess b3 in the holder and provided with an elongated is arranged to slide along the table B toward and away from the cutters and isclamped in the desired adjustment by means of a bolt n, the head of which is received in a dovetailed slot n (see Fig. 8) in the table and the screwthreaded end of which is provided with a tailnut n2. One of the important advantages of this arrangement is, it enables the operator to set the holder against the edge of the plate when placed widthwise between the cutter and the holder with the abutment m4 against the stop N, then clamping the plate M and the stop N in position, and, finally, placing the plate lengthwise between the holder and the cutters and clamping the holder in position by the hand-wheel k3. When the plate is operated upon in this direction, it may be turned to operate upon the adjacent edge by simply sliding the holder K toward the cutter until the shoulder m4 engages the stop N and then clamping it in position without taking the pains to again adjust it for the new cut. The stop and the holder having been adjusted for one plate of a series of smallersized plates, the whole series may be operated upon without further manipulation of the gage and stop.

For the purpose of placing the plate D in the proper position on the table for causing the cutter to follow a controlling-line on the plate, which may be the marginal line or an indicated line parallel with the marginal line which accompanies the etching or engraving upon the plate and which is often oblique to the edge of the plate proper, I provide the top gage O. The gage O may conveniently IOO IIO

consist of a rectangular piece of transparent y or translucent material-such, for example, as Celluloid or hornand provided with series of right lines o o', arranged in sets, the members of a set being parallel to each other and those of one set being at right angles to those of the other set. The gage O is held in rotary adjustment iu a swinging head P by means of a pivotal bolt p, provided with a clamping-nut p on its threaded end and having around its stem a spring p2 within the socket. The back of the gage 0 is provided with a grooved plate o2 and is adapted to slide along the face of the head-piece of's at the lower end of the socket and to be clamped in posi- 'tion by the nut p on the bolt p, the head of 'in position.

which engages with stop-pins p3 and p4 on the socket-piece P. The tension of the spring p2 tends to hold the gage O normally in position with its pin o4 against the pin p4.

The socket-piece P is pivoted on a bolt q, extending through the branches of the bifurcated end of the rod Q, and provided on its threaded end with a tail-nut q for holding it The rod or stock Q is held in longitudinal adjustment in a split sleeve q2, connected by arms g3 and Q4 with a hub Q5, mounted to rock on or together with a rod Q6, supported in brackets a2 on the frame A. The su pporting-sleeve q2 is permitted, either on or together with the rod (16, an adjustment forward and backward to bring the gage-carrying rod Q in the desired position relatively to the plate to be adjusted, and the stock Q may be adjusted longitudinally in the sleeve q2 to bring the plate into its proper relation laterally of the table to rest upon the plate to be adjusted, while the gage itself when resting upon the plate may, if made transparent or translucent, as is preferable, be readily utilized to make one of its lines 0 or o' register with a marginal or other controlling line on the plate, thereby placing the plate on the table in such a position that when clamped and fed to the cutters they willcut aline parallel with the marginal or controlling line on the plate. After the gage O has been utilized to adjust the plate in this manner it may be thrown back into the position shown in Fig. 1 out of the way of the operator, who may then feed the plate to the cutter, as may be desired.

The particular advantage of the gage O lies in the fact that it may be made to rest on a controlling-line of the plate at the central part of the plate 0r a considerable distance from the edge of the plate, such a line being frequently the line which is to control the squaring of the plate rather than a line nearer the margin.

The gage O, being readily removable from the head-piece o3, admits the substitution at pleasure of gages of different kinds and having lines or points at different intervals apart to suit the work of a coarser or finer grade, as may be desired.

The several clamps, holders, and gages which have hereinabove been described place within reach of the operator standing at the front of the machine sufficient means to enable him with great facility to adjust plates of varying sizes and thicknesses into proper position to receive the desired cut, while special care has been taken that the several devices do not in any serious manner obstruct his movements in performing the cutting operation in an expeditious manner.
